Abstract

In a molecular beam forming apparatus, nitrogen or helium is supplied to the reservoir 1 through the valve 2 and is discharged through the nozzle 3 into the expansion chamber 4, from which it flows, through the divertor 6, into the intermediate chamber 5. Gas from 5 flows through the divertor 8 into the chamber 7 where the beam is formed. The maximum intensity of the beam is produced when the following relationship is satisfied:- where b = axial distance between 3 and 6 D 0 = diameter of orifice 3 Kn o = Knudgen number of the gas in chamber 1 P 0 = pressure in 1 P1 = pressure in 4.
